mounted in connection with the motor and motor shaft; I i i Fig. 6 is a plan view of one form of an end cutter mounted upon the shaft;

Fig. 7 is a vertical section of the cutter shown in Fig. 6; p Fig. 8 is a section taken pon the line 88 of Fig. 2 in the direction indigated and showing means for adjusting the pillar about its axis; and v r v Fig. 9 is a broken plan view of the mounting sleeve end of the motor bracket.

Referring to the drawings, the numeral 1 is used to designate a ase having a vertically disposed portion 2 recessed to receive thelower end of a pillar 3 10tatably'Ii10lll1t ed therein and extending vertically upward therefrom. The pillar 3 is hollow and has a slot 4 formed in one side thereof. A top plate .6 isse'cured upon the top of the pillar 3, said plate beingfdispos'ed in a horizontal planeand vbeingslotted as at '7 to'inatch with the slot l of the pillar. A collar 8 secured upon the pillar 3 to seat upon the u per end of the base portion 2, said collar hein rovided with a laterally extending handle 9 extendin aeross a: sector flange 11 upon the top of the base portion 2. A uitable securing member 12m handle 9 engages an .t'rreuate in the sector flange 11 whereby may be turned position.

the pillar and secured in a des'ir'd Tried the 113 "f rmed a bracket 16 is slidably mounted upon the pillar 3. The bracket 16 provided with a bearing sleeve portion 17 engaging the pillar and having a tongue 18 extendi g into the illar through the slot .4. The

inner edge 0 the tongue 18 is provided with 66 threads 19' cut therein to engage a threaded shaft 21 rotatably mounted within the pillar .8, said shaft 21 being arranged to be rotated in any convenient manne as by a crank, not shown, inserted into a squared socket 22 formed in the upper end of the shaft, to raise or lower the bracket vertically relative to the pillar. The bracket 16 extends laterally from thepillar 3 upon the forward side thereof, and is bifurcated at its outer end to form arms 23' forming hear his ings for the ends of a motor mounting shaft 24 extending between the arms in a horizontal plane.

A suitable electric motor 26 is mounted between the arms 23 of the bracket 16 and supported upon the mounting shaft 24. The motor 26' is provided with a motor shaft 27 disposed at substantially right angles to the axis of the mounting shaft 23. One end of the shaft 27 is extended axially outwardly and provided with a slot 28 to detachably engage a suitable cutting tool 29 of any desired form. The end of the shaft 27 is provided with a tapped aperture 31 to receive a securing member 32 for securing the cutting tool 29 within the slot. The member 32 is also operative for securing a cutter 29 upon the end of the shaft, as shown in Figs. .6 and 7, as desired. 7

o A sector worm gear 33 is secured in any convenient manner upon the motor concentric to the mounting shaft 24. A worm 34 is mounted upon a shaft 36 rotatably supported upon the bracket 16, said worm 34 meshing with the sector 33; The shaft 36 is provided with a suitable crank 37 or other suitable turning means whereby the worm may be rotated to actuate the sector and motor to desired adjusted positions.

A guide bracket 38 is adjustably and detachably mounted in connection with the motor, said bracket preferably comprising a collar fitted onto a shoulder 39 upon the motor, a set screw 40 being provided for securingthe collar in a desired position upon. the shoulder. The guide bracket 33 -is provided with an arm portion 41 bifurcated atits outer endto sli'dably receive a guide member'42 adjustably secured upon the arm by means of a suitable clamping member 43. The clamping member 43 is adjustable along slots 44 formed in the bifurcationsof'the arm 41, and the guide 42 is provided'with a longitudinal slot 46 whereby the guide member may be adjusted longitudinally and pivotally upon the securing member.

A table 47 is pivotally connected to the top plate6, preferably upon the rearward side of the machine, by means of a suitable hinge mounting 48. The table normally rests in a horizontal position supported by the topplate 6,;and is arranged to be swung rearwardly to an inoperative position tilted approximately 15 from the vertical. The table is provided with an opening 49 immediately over the motor 26 to permit the shaft 27 thereof to extend upwardly through the 'table. A plurality of nesting bushings 5l are provided to seat within'the opening "49 upon a shoulder 52, the ends of said bushings 51 being arranged to lie flush with the surface of thetable whcrebythe opening 49 may be closed except for the space necessary to admit the shaft 27 through the table to operate a cutter above the plane of the table, as shown in Fi s. 2 or 4 of the drawings.

The motor 26 is connected to any suitable source of electrical energy and is controlled by suitable circuit control means, not illua trated.

In operation, the motor 26 is normally adjusted to a position such as shown in full lines in Fig. 2 of the drawings, with the motor shaft 27 extending vertically upward. A cutter 29 of desired form is secured upon the shaft 27, as shown in Figs. 4, In doing flat work, the table 47 is lowered to its operative position, as shown in Hi 2, the shaft 26 extending upwardly through the opening 49 so that the cutter is supported and operated above the planeof the table. Material to be shaped is then supported upon the table, and moved past the cutter in the desiredmanner.

For cutting irregular material, the table top 47 may be tilted rearwardly to an inoperative position, as indicated in dotted lines in Fig. 2. The shaft 27 is thus left exposed and the cutter is rendered accessible for cutting materials of irregular sha c lch as cannot be manipulated. or cut in the desired form when supported upon the table. The guide member 42 is adjusted to a .desired position relative to the cutter 29 where by the material may be supported in a nesired relation to the cutter said material is moved past the cutter.

For many kinds of work, it is desirable to have the cutter downwardly disposed so that the work may be presented to the cutter from below or the cutter moved downwardly upon material supported below the bracke For such purposes, the worm 34 is turned to rotate the sector 33 and motor 2-6 bout the axis of the mounting shaft 24 to the down-, wardly disposed position indiqied in dotted lines in Fig. 2. Any temporar surface may be placed below the cutter to support materials to be out, if des 'l, and the guide member 42 is carried with the motor so that said guide member rizy justed to a desired position relative to the cutter in its downwardly disposed position. I In many cases it is de irable to ave the motor shaft inclined at various am at positions between its extreme vertical position. The worm 34may be turned lo .aaljuJ-st the motor to any desired position between the extremeupwardly and downwardly disposed positions mentioned, and said worm serves to effectually lock the motor in any desired adjusted position. In Fig. 2 of the drawings, I have illustrated, in dotted lines, the manner in which the share 27 mm be ardesired cutting member. The guide member 42 beln normall carried with the supporting Y be rdtestifies motor may be'adjusted' as desired, or if the guide is 1 unnecessary for any particular Work, the guide may be entirely removed.

The motor and cutter may be raised or lowered to desired positions by an appropriate turning of the threaded shaft 21 so that the cutter may be adjusted and held at any desired vertical position, or the cutter may be raised or lowered past work held in a fixed position. The pillar 3 may be turned upon its axis by means of the handle 9 for adjusting the cutter to a desired position, or for moving the cutter past material held rigidly in a fixed position.
